All values are mean [correlation coefficient (r)] and 95% confidence interval after Fisher's z transformation. Correlations are shown when r = 0.0 is not part of the confidence interval and when r>0.5 or r<−0.5.
Abbreviations: SNS: sympathetic nervous system; PNS: parasympathetic nervous system; SC: skin conductance; HF power: high frequency power; B-BAES, brief biphasic alcohol effects scale; POMS, profile of mood states; PPW: postprandial wellness questionnaire; BT: body temperature.
